Wireless Local Area Networks

WLANs are standardized under the IEEE 802.11 series.

Common encryption technologies used by these networks are: WEP, WPA/WPA2-PSK, some networks have no encryption at all.

In order to decrypt intercepted secured WLAN traffic you should crack the encryption key. Note, that the only option for cracking WPA/WPA2-PSK keys is to do a brute-force password guessing attack. There are several WPA-PSK rainbow tablesavailable.

Many commercial network forensics systems can intercept and decrypt WLAN traffic, for example:
